Answer: k=9/4

Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:

>x^2 +3x +9/4

> (x+3/2)(x+3/2)

Perfect square.

The Lynn’s family bought a house for $75,300 a few years later they sold the house for $80,250 how much greater was the selling

Zepler [3.9K]

Buying price: $75,300

Selling price: $80,250

You want to find out how much more the selling price was when compared to the buying price.

To find the difference in prices, simply subtract the selling price with the buying price.

$80,250 (buying price) - $75,300 (selling price) = $4,950 (price difference)

The selling price is greater than the buying price of the house by $4,950
